The behavior of maximum likelihood estimates (MLEs) and the likelihood ratio statistic in a family of problems involving pointwise nonparametric estimation of a monotone function is studied. This class of problems differs radically from the usual parametric or semiparametric situations in that the MLE of the monotone function at a point converges to the truth at rate n (slower than the usual √ ...

Mixed Poisson regression models, a class of generalized linear mixed models, are commonly used to analyze count data that exhibit overdispersion. Because inference for these models can be computationally difficult, simplifying distributional assumptions are often made. We consider an influence function representing effects of infinitesimal perturbations of the mixing distribution. This function...

The article addresses foreign direct investment as an economic growth factor. dynamics of the main development parameters Poland and Ukraine is analyzed. estimates are based on such level, GDP, ease doing business indicators, index, freedom corruption perception etc. Poland’s advantages compared to other countries when establishing mechanism attraction determined. Special attention focused fact...

Although wildlife biologists need reliable estimates of white-tailed deer (Odocoileus virginianus) density to facilitate management, few studies have examined distance sampling as a density estimation technique for this species. We compared direct (i.e., spotlighting from road transects) and indirect (i.e., counting pellets on randomly placed transects) distance-sampling techniques for estimati...
